:Wright, Abbot sford, near Sydney,-New South Wales,lAustralia, assignors to Interchangeable Knives (Wright) 1 Limited, Sydney, New South L Wales, Australia; a company or New South Wales, Australia Application February 6, 1953, was). 655,535- In Australia liebruary 16, 1932 V q 1 Claim. '(o1.1c4- 29)- This invention relates toiclicking knives also known as dies used in boot, shoe and other leatherandlike goods manufacture to cut and punch out blanks such as the shape and pat-'- terning of uppers andsoles fo'r'boots and shoes and like blanks for bags, purses, braceset'cet'era, and which 'dies hitherto have. been made with the shapeand configuration ofthe blank and any desired inner configuration or patterning intel gral thus'necessitatingf the whole'to be made for each difie'rent; size 'and for.'eachdifferent inner configuration and/or patterning required thereby involving'considerable 'costand'tending to restrict .manufacture to a fe'widesigns' and' patternings. i Ul' i.

Now thisinv'ention has been-specially devised in order to .provide'an improved: clicking die or knife which has the main or outer die formed to the desired outer configuration and when desired also to theinner or to some of the inner configuration of an upper, et cetera, and is adapted for the ready application thereto or combination therewith of interchangeable auxiliary dies whether for cutting, punching, piercing, perforating and/or branding thereby enabling one main clicking die for each size to sufiice, and with the addition thereto of a desired auxiliary die or plurality thereof to click or form by one operation a blank such as a boot or shoe upper of desired inner configuration and any desired patterning formedtherein, thereby permitting the auxiliary die or dies to be interchangeably used with main dies of different sizes, which very considerably reduces the cost of clicking and patterning dies and consequently the cost of articles produced with the aid thereof, and permits.

marking, piercing and/or branding dies to be associated with the clicking dies for soles, so that guide markings or piercings, and/or a brand or other marking or printing will be made on or in the sole blank'as same is clicked or formed.

The improved clicking die comprises the usual main die or knife such as for a boot or shoe upper, or sole, a bag, purse or braces; blank, to required configuration, and size, provided with slots in its back or upper face at requisite positions, and for use therewith are provided improved auxiliary dies which have the functioning face formed to a blade or cutting edge to desired inner configuration and/or pattern or to c a marking orv piercing or perforating part or vparts and/or a brand, and have projections or arms at requisite positions to seat in the slots of the main die, and when desired the auxiliary die or dies is or are also provided with slots at requisite positions in its or their back or upper faceto receive'projwtions of an additional aux-.

iliary die or plurality thereof so thatan-addi-i tional auxiliarydie or plurality thereof imay be added to another auxiliary die and thus enable to be used therewithinterchangeable additional auxiliary dies. l

. And to permit the application of auxiliarydies w themain and an inner configuration die or-ito adjust the position of such dies as when anin-Q ne'r configuration die is to"be:arranged at desired longitudinal position of the main die the latter'has a plurality of slots in its back and a pattern or other die maybe constituted of'a die carrier consisting of arms with a socket formed therein and an armless die securedin. the said socket such as by a set screw, which construction and arrangement enables the one die to be used in different carriers having their arms disposed at respectively different angles so as to fitin the slots of the main die and the slots in the other auxiliary die or dies and hold the additional auxiliary die at desired position, or where an auxiliary die will permit, the arms may have a rabbeted slot therethrough and interchangeable dies may be emplaced therethrough and secured as bycountersunk screws. I i

To avoid having to lift out separately two or more auxiliary dies from a maindie to another main die the plurality of dies arranged toan inner configuration and patterning or patternings may be disengageably secured together in convenient 'manner so as to be movable as a unit.

In order that the invention and practical applications thereof will be readily understood and erence to the accompanying drawings in which;

Figures 1, 2 and 3 are back perspectives of an upper main die, an auxiliary inner configuration die and an auxiliary pattern die,

Figure 4 is a face perspective of the three dies assembled,

Figure 5 is a fragmentary perspective of a carrier for interchangeable auxiliary dies,

Figures ,6 and 7 are fragmentary back and face perspectives respectively of an additional auxiliary pattern die having an interchangeable functioning face, I I

Figure 8 is a fragmentary perspective of means for removably securing together an interchangeable die to the main die or interchangeable dies or dies'and die carriers together,

Figures 9 and 10 are back perspectives of another main die and a pattern die,

slots 17 formed in its back at desired positionsr' and an auxiliary inner configuration die18 has projecting arms 19 at requisite positions with re: duced ends 20 to form shoulders so that when the die 18 is applied to and' corii dried-wfiHthe main die'16, the arm ends- 20' 'willseatflfii the slots 17 and the die 18 win be'held'ifi correct position in relation to the di'lfil H I When it is desired to cut or form patterning from or on the upper orbtlier blank? a, slot d? slots 21 is preferably provided in the inner cm figuration part of the main die or in such a die associated with said main die, and an auxiliary or patternidie 22 (Figure 2') having stub-arms 23 andarrns'24 whichmayhave slotsg25 near their ends is: applied to the dies 16 and 18 as shown in Figures 1 and 4-; also Qarxd 11, and when apattern' die will permit: anadditional pattern die 26 (Fig ure's- G and 7) may be applied thereto and/or the main die 16 in the same manner, that isib yarmsseatedin slots. a Hg 7 a v Instead of anauxiliary die being ,made integral ar'm's'of which those laterally dis'posed: may not fit in the slots of the main die when its other arms are engaged-in other slots of said main die" or in the slots of other auxiliary dies; an auxiliary die carrier .(FigurevS) is providedand and a' s'ock'et27 for reception of an armless di'e 28 which is secured such as by a set screw 29,

or the die carrier may be formed as in Figures 6 and 7 with a rabbeted slot 30 for the die 26 which will fit thereinto and can be secured by sizes may be mtercl'lange'aibiei f When desired interfitting dies or dies and di holders may be removably secured together such as by screws-33 in Figure 6 or screws 34 in Fig-' ure 8.
